Abstract :
The assumption that the white noise sources independently affect the phase noise and jitter in ring oscillators is revisited. Propagation of jitter originating from a noise source around the ring oscillator loop and its effect on phase noise are quantified. It is shown how, contrary to the commonly-held assumptions, the resulting jitter can in fact depend on the number of stages.
